HENRY STANLEY, OF WEST POULTNEY, VERMONT.

COAL-STOVE.

Specification forming part of Letters Patent No. 3,876', dated January 4, 1845; Ressued April 10,

To all 'wh-0m t may concern Be it known that I, HENRY STANLEY, of lVest Poultney, in the county of Rutland and State of Vermont, have made certain new and useful Improvements in Stoves or Apparatusfor Heating Apartments, which I denominate Stanleys Coal-Burner; and I do hereby declare that the following is a full and exact descript-ion thereof.

In the accompanying drawing, Figure l, is a front elevation of my stove, and Fig. 2, a vertical'section thereof through its middle from front to back.

This stove is formed in what I denominate two stories, a lower and an upper, the main body of each of them consisting of a cylinder A, and A', Vand of four radiating flues, B, B, and B, B, giving an exterior form to each of them, such as is shown in .the horizontal section, Fig. 3, made through the middle of the lower story; but somewhat varied, asv will hereafter appear, in the upper story. The cylinder, A, and the radiating fines, B, B, rest on the upper plate, a, a, of the plinth, C, C, in which plinth there Vis an ash drawer, D. The said cylinder and flues extend upward to the lower plate, b, b, of a chamber, E, E, situated between the two stories. The horizont-al plates a, a, and b, b, have circular openings through them corresponding in size with the cylinder, A, and four triangular openings corresponding with the four triangular radiating lues, B, B.

In Fig. t, the plate, b, is shown, the upper story of the stove being removed; c, c, are the four triangular holes through said plate, corresponding with the place of the radiating flues, B, B, below them. The firechamber which extends from the grating, d, CZ, near the bottom of the lower cylinder, up to the plate Z), b, is lined with fire brick, e e.

7 Fig. 5, is a top view of the plate a, a, having, like the plate b, b, a large center opening through it corresponding with the rechamber, and four triangular openings, c', c', corresponding with the radiating ues B, B, which are to rest upon and embrace them.

D, is the ash-drawer, and this is surrounded by a partition, g, g, which extends from the bottom plate f, f, of the stove, to the plate a, a; leaving a flue-space in the plinth on each side and at the back of the ashdrawer, through which the heated air that is to descend through the front radiating flues may pass to the back ones, up which it is to ascend.

Between the upper and lower stories there is an intermediate, or middle, chamber, E, E, which extends from the plate b, up to the plate 7L, i, upon which the four radiating iues B, B, and the cylinder A, of the upper chamber rest. Fig. (i, is a view of this intermediate chamber, supposing the lower story to be removed (including its plate, .7), Z2) and the eye to be directed upward toward the upper chamber; z', z' is a conical partition extending from top to bottom of the chamber, E, its upper edge coinciding with the lower end of the cylinder, A and its lower edge resting on the upper plate, b, b, of the lower story; and, of course, embracing the cylindrical fire-chamber. The intermediate chamber is divided into two compartments, an anterior and a posterior, E, and E', by partitions, j, j, one of which is shown by dotted lines at j, Fig. 2. The conical partition z', z', has perforations through it, as shown at k, la, to admit the heated air, and gaseous products of combustion from the tire-chamber into the anterior chamber, E ,but they do not enter the posterior chamber until they are about to pass off at the exit pipe, F, Fig. 2.

The radiating ilues, B, of the upper story, rest on the plate h, 71 of the intermediate chamber, and include the triangular holes o, c, Fig. 6; they extend up to the cap, or cornice chamber, G; into the anterior part of this cap chamber IA make a number of holes, Z, Z, through the upper part of the cylinder A; which openings are found greatly to increase the radiation from the cap, and the whole upper port-ion of the stove; behind these holes, as at the place of the dotted line m, Fig. 2, there are partitions in the cap space G, cutting ott' the passage along them, back to the exit pipe; but the rear portion, G', of the cornice space communicates with the box, or channel, H, Yat the back of the upper story into which the exit pipe opens. The two rear radiating flues, B', open into the space G.

Fig. 7 is a horizontal section through the middle of the upper story. H, is the flue space in its rear, from which proceeds the exit pipe F, and which opens above into the cornice space, G; and into the lower part of it there is, also, an opening through the plate, 7L, as seen at n, n, Fig. 6, principally in dotted lines. The respective openings, chambers, and flues which I have thus described, serve for the passage of heated air when it is intended to circulate through the radiating lines; but I also make the ordinary provision for allowing a direct passage from the fire chamber to the exit pipe.

For this purpose, I place a shutter, or

damper, o, 0, in the rear of the upper cylinder, A, through which there is an opening to which it is adapted; this opening leads into the space H, andthe damper may be managed by a handle, 77, or otherwise; r, r, Fig. LI, is a rod by which the grate may be vibrated; s, s, Fig. l, is a small'door opening just under the grate, either for regulating the draft, introducing` a poker, or tilting the grate, so as to drop the contents of the fire-chamber into the ash-drawer; t, t, are openings which are made on three sides of the upper cylinder, and which are furnished with sheets of mica; the front opening is in a door through which the fuel is to be introduced.

`When the fire has been kindled in thisk coal burner, and the damper 0, o, has been closed, the heated gases from the fire-chamber will, in great part, pass through the openings, it, 7c, in the conical partition z', z', and into the anterior chamber E; they will thence descend through the front radiating iiues, B, B, and pass along the spaces in the plinth to the rear radiating fines, and up them into the posterior chamber, E; a portion of the heated gases will pass thence directly into the flue space H, through the opening n, n, in the plate 7L, Fig. 6; another portion will find its way to the exit pipe, by passing through the rear radiating flues of the upper story, into the cornice space G, and thence down to the eXit pipe. I have sometimes essayed to pass the whole draft up through these radiating flues, by closing the opening n, n, but the general draft is thereby obstructed; the opening ma, is, therefore, necessary to the proper action of the stove, and when this is not made too large, there will be an abundant draft up, and radiation from, the rear fines. The heated air which rises directly up into the cylinder A, passes through the openings Z, Z, in its upper end, into the anterior cornice space G, and creates a descending draft through the front radiating flues B, into the chamber E, and then takes the same course with that which had passed through the openings 7c, 7a, namely, down the front radiating fines, B, B.

Having thus, fully described the manner in which I construct my coal burner. and shown its o peration as resulting from the particular combination of its respective parts, what I claim therein as new, and desire to secure by Letters Patent, is

The manner in which I have combined and arranged the two stories thereof, consisting of two cylinders, with the eight triangular radiating ues Varranged around, and in contact with, them; said fiues Communicating with the flue space in the plinth,

with the intermediate chamber, and withV the cornice space, as described; the two latter being divided by partitions into anterior and posterior portions, in the manner and for the purpose set forth; and there being, also, openings, such as are herein described and represented, through the upper end of the upper cylinder into the cornice space, in the manner and for the purpose above made known; it being distinctly understood that I do not make any claim to either of the individual parts, taken separately and alone; but that I limit my claim to the combination and arrangement thereof as a Whole; not intending, however, by this claim to confine myself, in constructing my stove, to the particular form of the respective parts, as described and represented, but to vary these as I may deem expedient while I attain the same end by means substantially the same.

HENRY STANLEY.
